000 AXNT20 KNHC 050552 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0605 UTC Thu Nov 05 2020 Tropical Weather Discussion for North America, Central America Gulf of Mexico, Caribbean Sea, northern sections of South America, and Atlantic Ocean to the African coast from the Equator to 32N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0530 UTC. ...SPECIAL FEATURES... Tropical Depression ETA continues to produce heavy rains and life-threatening flooding to sections of Central America. The center of Tropical Depression ETA, at 05/0300 UTC, is near 14.2N 86.3W. This position is also about 100 nm/185 km to the SSE of La Ceiba in Honduras. ETA is moving toward the WNW, or 285 degrees, 6 knots. The estimated minimum central pressure is 1003 mb. The maximum sustained wind speeds are 30 knots with gusts to 40 knots. Precipitation: scattered to numerous strong is from 150 nm to 360 nm from the center in the E semicircle, in the coastal waters from Honduras to Costa Rica; and from 150 nm to 250 nm from the center in the NW quadrant in Honduras, Belize, and Guatemala. Scattered moderate to isolate/widely scattered strong is within 180 nm of SW Cuba. Other isolated moderate to locally strong is elsewhere, from Hispaniola westward, including in Central America. Please, read the latest NHC Public Advisory at: https://www.nhc.noaa.gov/text/MIATCPAT4.shtml, and the Forecast Advisory at https://www.nhc.noaa.gov/text/MIATCMAT4.shtml, for more details. Rainfall will lead to catastrophic, life- threatening flash flooding and river flooding, along with landslides in areas of higher terrain of Central America. Flash flooding and river flooding are possible in Nicaragua, Honduras, Guatemala, Belize, Panama, Costa Rica, El Salvador, southeastern Mexico, Jamaica, and the Cayman Islands into western Cuba. ...TROPICAL WAVES... An Atlantic Ocean tropical wave is along 40W/41W from 16N southward, moving westward 10 to 15 knots. Precipitation: no significant deep convective precipitation is apparent in satellite imagery. An Atlantic Ocean tropical wave is along 55W/56W, from 15N southward, moving westward 10 knots. Precipitation: scattered strong is from 01N to 05N between 51W and 62W. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal plains of Senegal near 15N17W, to 10N20W, and 07N26W. The ITCZ continues from 05N to 07N between 26W and 38W, and along 05N/06N between 41W and 50W. Precipitation: widely scattered moderate to isolated strong is from 02N to 11N between 10W and 36W, and from 12N southward between 45W and 60W. GULF OF MEXICO... Broad surface anticyclonic wind flow covers the Gulf of Mexico. A surface ridge passes through Louisiana, TO 22N98W in coastal Mexico. Rainshowers are possible, to the south of the line that runs from the Florida Keys, to 23N90W in the south central Gulf of Mexico, to the coast of Mexico along 20N97W. Any possible precipitation that may be from 90W eastward is related to Tropical Depression ETA. Strong high pressure, extending into the region from the western Atlantic Ocean, will maintain fresh to strong NE winds in the southeastern half of the basin, through early Friday. The wind speeds will remain fresh to strong in the eastern Gulf of Mexico during the upcoming weekend. The remnant low of Tropical Depression ETA will re-intensify into a tropical cyclone on Friday night in the NW Caribbean Sea. Tropical storm conditions are possible in the Florida Straits on Saturday night and Sunday. CARIBBEAN SEA...
